Results of the linear regression analysis performed with and without weighting of the data are shown. Comparisons among rest and the different exercise intensities were made using a one-way non-repeated analysis of variance with the data obtained from subjects for whom there was a significant linear relationship between DAP and burst strength. The data presented are group averages from subjects for whom there was a significant linear relationship between DAP and burst strength ± s.e.m. Abbreviations are same as in Table 1.
